Current Building Regulations
The required ‘U’ value for new insulated buildings or for a refurbishment project is below 0.30 W/m²K.

Typically Jablite External Insulation specified to a thickness 110mm or 120mm will achieve the required u-value of 0.30 W/m²K as part of an insulated render system on a solid wall. In addition you can specify 70mm or 60mm for specific areas where 90mm is not suitable – for example in the alleys of adjoining properties.

External wall insulation (EWI) can be installed without having to re-locate the occupants of the property; it will:

Yes. Jablite standard products use between 0% and 60% recycled material depending on the grade, type of product and recycled material availability.
The recycled material is from off site sources e.g. clean offcuts from building sites or from the manufacturing process - 100% of Jablite's manufacturing EPS waste goes back into the manufacturing process.

Is Jablite packaging environmentally friendly?

Jablite is continuously striving to reduce packaging on its products. Products are wrapped in film as and when necessary to protect them during transport and storage on site. Ongoing efforts have been made to minimise the thickness of film used to reduce the packaging further.
Pallets are used when requested by customers, but wherever possible recyclable EPS 'skids' are used.
